With a name like Carmichael, you'd figure Ricky over here would be into cars. The championship motocross rider is actually more into two-wheeled vehicles than four, but that doesn't mean he can't show some enthusiasm for the automobile. Last year he worked with Chevy on a special Sonic concept for the SEMA show in Las Vegas, and now they've rekindled the partnership for the special truck you see here.

Hype surrounding this year's Specialty Equipment Market Association (SEMA) show next month started months ago, and automakers and aftermarket companies alike have been previewing the vehicles that attendees will be able to see on the show floor. Chevrolet now can officially be added to that list, as it recently announced seven "performance-oriented concepts" it's bringing to the show.
